Step-by-step explanation:
f(x) = x / (x - 7) = 1 + 7 / (x - 7).
The domain of f(x) depends whether the denominator of the rational expression is non-zero.
When (x - 7) = 0, x = 7.
Hence domain of f(x)
= All real values of x excluding 7. (C)
(A)
Choice (B) is not the right answer because I
it's only 3rd order. But because f(x) goes to negative infinity when x goes to positive infinity means that the right answer is (A).
Answer:
f(g(- 2)) = 5
Step-by-step explanation:
Evaluate g(- 2) then use this result to evaluate f(x)
g(- 2) = (- 2)² - 5 = 4 - 5 = - 1, then
f(- 1) = - (- 1) + 4 = 1 + 4 = 5
Answer:
the number of children has red or brown hair is 
.
Step-by-step explanation:
We have been given that in Marci's family there are total 6 children.
Out of 6 children
Number of children have blonde hair = 
Number of children have red hair = 
Number of children have brown hair = 
Since, we have to find the fraction of children has red or brown hair=
Hence, the number of children has red or brown hair is
